Which of the following diagrams correctly represents the formation of a compound consisting of magnesium and fluorine?

See explanation

Explanation:

The image attached describes the formation of magnesium fluoride.

Magnesium has two valence electrons while fluorine has seven valence electrons. Magnesium can now transfer one electron each to two fluorine atoms thereby forming the compound MgF2.

This has been shown pictorially in the image attached to this answer.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
